Starches provide a (partial) alternative to talc and mica. Starches can
- absorb sebum,
- enhance skin feel,
- and improve the stability of pressed powders.
Corn starch has a similar particle size range to that of mica (2 – 25μm) whereas rice starches are even finer (approx. 8μm) and exhibit an extra ordinary soft-touch. The large surface allows a fine distribution of both functional and active ingredients.
